8-Bit Shift Register (S-IN, P-OUT)

The TC74VHC164 is an advanced high speed CMOS 8-BIT

SERIAL-IN PARALLEL-OUT SHIFT REGISTER fabricated with

silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

It consists of a serial-in, parallel-out 8-bit shift register with a

CLOCK input and an overriding CLEAR input.

Two serial data inputs (A, B) are provided so that one may be

used as a data enable.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• High speed: fmax = 175 MHz (typ.) at VCC = 5 V

• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C

• High noise immunity: VNIH = VNIL = 28% VCC (min)

• Power down protection is provided on all inputs.

• Balanced propagation delays: tpLH ∼− tpHL

• Wide operating voltage range: VCC (opr) = 2 to 5.5 V

• Low noise: VOLP = 0.8 V (max)

• Pin and function compatible with 74ALS164

Note: xxxFN (JEDEC SOP) is not available in

Japan.
